We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

A 3D physics body that simulates the behavior of a car.

This physics body implements all the physics logic needed to simulate a car. It is based on the raycast vehicle system commonly found in physics engines. Aside from a [CollisionShape3D] for the main body of the vehicle, you must also add a [VehicleWheel3D] node for each wheel. You should also add a [MeshInstance3D] to this node for the 3D model of the vehicle, but this model should generally not include meshes for the wheels. You can control the vehicle by using the [member brake], [member engine_force], and [member steering] properties. The position or orientation of this node shouldn't be changed directly.
|
|
[b]Note:[/b] The origin point of your VehicleBody3D will determine the center of gravity of your vehicle. To make the vehicle more grounded, the origin point is usually kept low, moving the [CollisionShape3D] and [MeshInstance3D] upwards.
|
|
[b]Note:[/b] This class has known issues and isn't designed to provide realistic 3D vehicle physics. If you want advanced vehicle physics, you may have to write your own physics integration using [CharacterBody3D] or [RigidBody3D].

Slows down the vehicle by applying a braking force. The vehicle is only slowed down if the wheels are in contact with a surface. The force you need to apply to adequately slow down your vehicle depends on the [member RigidBody3D.mass] of the vehicle. For a vehicle with a mass set to 1000, try a value in the 25 - 30 range for hard braking.

Accelerates the vehicle by applying an engine force. The vehicle is only sped up if the wheels that have [member VehicleWheel3D.use_as_traction] set to [code]true[/code] and are in contact with a surface. The [member RigidBody3D.mass] of the vehicle has an effect on the acceleration of the vehicle. For a vehicle with a mass set to 1000, try a value in the 25 - 50 range for acceleration.
|
|
[b]Note:[/b] The simulation does not take the effect of gears into account, you will need to add logic for this if you wish to simulate gears.
|
|
A negative value will result in the vehicle reversing.

The steering angle for the vehicle. Setting this to a non-zero value will result in the vehicle turning when it's moving. Wheels that have [member VehicleWheel3D.use_as_steering] set to [code]true[/code] will automatically be rotated.

|
[b]Note:[/b] This property is edited in the inspector in degrees. In code the property is set in radians.
